The Study on the Flocculation Effect of Modified Collagen Protein Cationic Flocculent on Waste Drilling Fluid

Abstract:

Glyoxylic acid was used to carboxylic collagen protein which obtained by the hydrolysis of gelatin. Al (Ⅲ) was complex to it with aluminium tanning principle in tanning chemistry and the novel flocculent (CGAl) was prepared. Use CODcr removal rate, suspended solid and chroma to indicate the flocculation effect on waste drilling water. The results indicated that when CGAl was used, its dosage was 10.5g/L and the range of pH and temperature were widely. After flocculation, CODcr removal rate was 92.3%, suspended solid decreased from 2115mg/L to 65mg/L, and chroma reduced from 1003 times to 6 times. So the flocculation effect was obviously.
